I've only used it once, but it's been stored at home for a long time. The zipper pull tab is torn off, possibly caught on something. Please check the third image. Other than that, I think there are no particular stains, but there might be something I missed. This umbrella case can be attached to the handles of business bags, tote bags, and shoulder bags. -------------------- Compatible size: Total length 30cm, umbrella circumference up to 19cm * When the umbrella is folded Material details / ● Material: Outer / 100% polyester (coating: vinyl chloride) Inner / 90% polyester, 10% nylon ● Size: Approximately 32 x 10cm ● Country of origin: China Please note / * Depending on the design of the umbrella, it may not be possible to store it.
